OVTune VF Tuner | OVTune - Tacoma ECU flash tune options and feedback

That's odd. So from that it sounds like the tune processes speed data from a speed output source. So it's not actual speedo, but a "tool".

I think my bike updated the odometer without calculating my sprocket change. Like it racks up miles faster.

Does the odometer go by actual or what it thinks? I guess if it's programmed for factory settings, does it go by number of rotations?
So bigger tires means you'll be going faster. Does the odometer rack up faster then? Does it get factored into miles until empty? Shower lower mpg?

@TermLimits - Can you answer this for me? :) Overthinking.

I just noticed this post.

The truck calculates everything by what it thinks, exactly how you described.

For me, 37” tires means I’m going about 84 mph when my truck says I’m doing 70 mph. The mpg is also inaccurate like this. But the numbers displayed and the actual numbers are relative so you can kind of convert them subconsciously. There’s also some conversion tools here: https://tiresize.com/speedometer-calibration/

Here’s a silly one: When my low gas light comes on, it says I have about 110 miles until empty. I think a stock truck puts that light on around 30 miles to empty.

This is going to mess with me. Time for a speedohealer. Lol.
 
So a calibrator won't fix mileage remaining.

The only thing that the calibrator does not fix, however, is the “total mileage” that your tank reads when you fill up with a full tank of gas. This will still read incorrectly depending on your “non-stock tire size” and “non-stock weight” your truck modifications added to your stock curb weight.

Says the module changes shift points. Would that effect or override tunes that are flashed?

Guess my biggest thing is if I want to pay $75 more just to have a black box. Seems they are the same module and you can use Hypertech software direct from their site for the Rough Country. Just don't want RC anything since I'm a quality brand whore.

I'm honestly not sure as I've never run into one in the wild here lol.

If you get one and notice that your tune shift points are off from what they should be, a simple change to a stock gear ratio/tire size tune could remedy it. Sounds like the hypertech acts as a go-between and/or it modifies the signal that is provided to the ECU to spoof the speed relative to the tire size selected.

50/50 on whether or not it will mess with a tune. Probably a simple fix if it does
 
Just installed VFtuner on a laptop running Windows 10. Installation seemed to go well, but the program won't open. Any ideas?

What happens when you try?

Uninstall.
Re-install.
Restart.
Right click shortcut, Run as Administrator?

Yep, did all that.
Nothing happens. Little blue wheel spins for about 2-5 seconds, then nothing. Nothing shows up in task administrator, nothing in the minimized box, nothing on the desktop.

Where did you download it from? Newest version? Try uninstalling. Download from another source? Maybe the executable installer was corrupt?
Have an internet connection?

It would still start up though.

Yep. Did that too. Downloaded latest version (1.4.1, 9-18-21) from vftuner website. Internet connection works. Reinstalled, restarted. Waited.
Matthew suggested the things you did, still waiting. I'm sure it's something on this new (cheap!) pc I bought just for the purpose.
 
Is it a laptop?
Try something like CCleaner. Clean up corrupt registry files.

Instead of launching it with the shortcut did you try going to the destination folder of the file and launch it from there?

Literally just bought the computer for this project. Nothing to clean up. And yes, did try to launch it from the original folder.

Even a fresh install on a new machine can have corrupted files. Possibly needs to go through Windows updates since being made?

Will give it a shot. Tried the windows update thing. This experience is reminding me why I went with all apple products 10 years ago.
 
Short review of Valley tune-removed it after 1500 miles
Long review of Valley tune-
1500 miles of mixed driving. anything from picking kids up at school to interstate driving and an 5 day off-road adventure.
Truck is a 17 Tacoma DCSB TRD OR, lifted, RTT, aluminum bed rack, Winch, Hybrid bumper, High clearance rear bumper with tire swing, 5.29 gears, blah blah blah, 34" tires 17" rims, Roof rack, snorkel, Sliders, Aluminum Skids (this trip) also have steel. Big AGM battery, URD Y pipe, TRD exhaust after that and chopped at the axle. Basically the truck has some weight to it.
My driving style is not aggressive. I don't have any need to beat anyone off the line at a stoplight. I sometimes like to floor it for fun but seldom do. I sometimes drive spirited but most of the time drive like a calm cool and collected person.
My tune before this was OV tunes v2.0 35's premium 5.29 without the thx
My impressions from the very start where not very good. I started with the standard tune for 5.29 gears and 34" tires. Throttle was so excessive that I immediately went to the light. Still the throttle seemed excessive. I contacted Valley tune and was advised to reset learned values. So I did. It didn't change. The problem with the throttle in both the standard and the light versions is that the first 1% of the throttle is 10% of it. It is real jumpy. Picking up kids from school and slowing moving forward with a light touch on the pedal was to much. Off-roading and trying to get just a little to get up and over something sent you up and over with too much. I spent 5 days in southern Utah on easy to difficult trails. Disliked the throttle the whole time. My other reason for removing the tune was it seems to shift too early when you have moderate throttle. Example getting onto the interstate. Getting on the pedal but not flooring it the truck would shift way to quick into 3rd or 4th and loose its quickness. reminded me of previous OVtunes maybe 1.04 or 1.03.
Next reason about me not liking it. This might be why some like it. The truck felt like it was in a half way ECT at all times. ECT was fine but not as good as it used to be with OVtunes latest tune.
I am unable to comment on gas milage because I dont keep track before. I know I can leave my house and get to Spanish Fork Utah on one tank of gas. The wind was really bad this time so I stopped near Hill AFB. About 80 miles short. Again wind was bad and drove 80mph the whole time. My truck does best at 75mph or less for MPGs.
The engine did sound different. Less noise but I have grown to like all the noises of this engine. I did like the exhaust sound when coming to a stop with or without ECT on.
The last thing. I havn't felt like I had a dead pedal for a long time. Stock toyota without tune has the dead pedal feel. This is where you wanna go slightly faster at 60+ mph give it gas and it does nothing, give it more nothing, give it more and all of a sudden you are dropping two gears and going faster than you wanted to go. This tune does that.
Here is the thing though this is my opinion and anyone who has followed OVtune from the beginning knows how many different opinions are out there on what the perfect tune should feel like. My truck is not the perfect setup. It carries extra weight with all the armor and stuff. Add in all the camping gear, water and food and its a heavy truck. So maybe the truck would work better without all that extra stuff. Maybe its the perfect tune if all you have is 5.29 gears and 34's? I dunno because thats not my truck. The pricepoint is at a place where you can try it and not cry if you don't like it. Best wishes to everyone and God Bless America!!!
 
Looking for a Tuner in NC, to detune my OV tune 91 tune to an 87. Just not worth it in my opinion. premium gas is 90 cents more than regular.
 
Every Tacoma Owner i've tuned is very Happy with their Valley Runner tune. From a Stock Tacoma, lifted Tacoma to an Overland Tacoma with Cap, Tent & Camping Gear. 1000+ LBS. I do follow up on Customers.

I have run it for over 6 months now - No issues with it. No Jumpy Pedal at all. I'm on Standard Pedal setting. I daily drive it in traffic - 100 miles.

Im havin a good time with the CVC 3.0 tune. The rears broke loose a little bit on a downshift when i floored it the other day. Surprised the shit outta me. Been real smooth otherwise. On OV 2.0 i was flooring it all the time to get up to speed. I think ive only had to do it 2 times on the CVC.

That's good to hear. I'm getting that tune this Sunday. How do you use your truck? It sounds like a fairly conservative tune that should work well for daily driving and off pavement. Is that your experience?

It's pretty good, feels like what it should have from the factory. Cures the gear hunting and has much more consistent power. I haven't tested it in the hills yet or tracked my MPG for long. I'm lucky to live near the guy who developed the tune so I talked to him while he flashed my truck. I recommend it. Unfortunately it seems it has kind of limited distribution right now

On the list of my 1000 to-do things for T3G, making a little chart of the different ECU flashes, what they feel like, and their website, is #698.
 
If someone knows the names of the most popular tunes, please post them. I want to add their names to the title of this thread so people see it when they search.
